N55 Turbo Side Intake Progress

[Kdjm89]

All of those things sound good in my opinion. Removing the gearbox heat exchanger can obviously effect how long the gearbox can take to warm up, but the trade off of this depends on what you use the car for and your climate. Though the proper thermostat should offset some of the negatives of removing the heat exchanger. Some of the DCT boys can chime in on their setup here I’m sure.

If you’re in the UK and want a CSF manual radiator, I have one spare.

I’m not hugely fussed about the heat exchanger, the joints to the rad have caused me no end of headaches since fitting the DO88 radiator. Car only ever gets used for track days (last used for a ring trip in Nov 24, next use is a ring trip in April)

Ooooo I am UK based, how much would you want for the CSF?

Wanted to give the thread a bump… anyone have any new progress with there hot side intakes? I finally got my ATM 335D intake but gonna have to remodify the side where the intake goes through because doesn’t exactly line up with the n55s lol, plus have to do some cutting due to the ac hose routing. Gonna most likely just go to a machine shop and have them remake me that side out of sheet metal with all the cuts and slots where they need to be

My first PLA prototype is hot off the printer, she’s a good start, needs a few tweaky tweaks, but overall pretty good.

Currently the MAF sensor (when installed) clashes lightly with the A/C pipes, so I’ll move it to make a little more room.

With the aFe filter I have chosen.

The bonnet (hood) closes just fine too on my E8x, not sure about E9x as there is a little less room. I may make a version that uses the OEM S65 filter, we’ll see, but for now, a decent start.

Awesome, great update!

Nice job!!!!!

Very nice! I’m assuming you shaped it after the stock maf housing? Any idea on the circumference? I feel like all these aftermarket intakes for our car do 3 inches and run fine with no maf issues but weirdly enough when I had the 3 inch housing from MRP I used to always get lean codes, but I don’t know now if that also had to do with any pcv related issues, since I went mafless and deleted the pcv since then lol

Thanks! And correct, I have replicated the standard MAF cross-section. The OD of the standard MAF is equivalent to roughly 3.9” round tube and the standard plastic wall thickness is between 2mm to 2.5mm (0.1”). My thinking is that the standard MAF cross-section (though oddly shaped) is big enough for my case and I was less likely to have errors. That’s the theory anyway! I will get a circumference for you when I go on my computer next.

How have you deleted the PCV?

My math is horrible, so what would that equate too as far as inner diameter? And using the Ross racing pcv delete cap, that gets rid of the pcv diaphragm and essentially “plugs” the head ports and lets the crankcase vent to air. I had it pictured here on an older post, I’ll try to take a updated picture when I have the chance
